x.cpp:22:11: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
22 | printf("%s = %s\n", &N1[0], &N2[0]); // warning
| ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Side issue... It's not clear what a "directive" or a "directive argument"
is here, without guessing. "%s" is called a "conversion specifier". "null"
is not a defined anything either, and the highlight should ideally be on the
argument, with maybe an extra info one for the conversion spec.
So maybe something like
x.cpp:22:11: error: argument to ‘%s’ is a null pointer
[-Werror=format-overflow=]
22 | printf("%s = %s\n", &N1[0], &N2[0]); // warning
| ^~ ^~~~~~
